Application October 17, 1935, Serial No. 45,395

4 Claims.

This invention relates to a stop that can be readily connected to a strap, rope, wire, chain or the like, in position to strike a fixed member when the strap or wire, etc., is moved longitudinally of the strap, in order to prevent further movement thereof. The stop is so connected to the strap or the like that it cannot be moved 1ongitudinally thereof when the strap is taut or tension is applied thereto in opposite directions on opposite sides of the stop.

The invention is especially useful for straps which are used for attaching antiskid devices to automobile wheels and will be particularly described in this connection, but it is to be under stood that the invention is not restricted to this use but is applicable in other places and on other devices than in connection with anti-skid devices.

The invention will be understood from the description in connection with the accompanying drawing, in which Fig. 1 is a plan view of an illustrative embodiment of the invention; Fig. 2 is a section along the line aa of Fig. 1; and Fig, 3 is a section through an automobile rim and tire illustrating a use of the device.

In the drawing reference character I indicates a strap of fabric, which is preferably waterprooied, or the strap may be made of leather or other flexible material that preferably possesses a considerable amount of rigidity but is nevertheless capable of being somewhat readily bent by hand. A rope, wire, chain or other flexible member may be used instead of the strap I. The stop 2 is rigidly held in position on the strap I when this strap is taut.

The stop 2 comprises a curved body portion 3, that is preferably made in the shape of a section of a cylinder that is slightly longer than the width of the strap I. The body portion 3 may be bent on a gradual curve so as to be concave on one side and convex on the opposite side, or the sides may have plane surfaces that join each other at angles to provide a gradually bent portion 3.

A lug 4 for contacting with a fixed object or obstruction is provided on the convex side of portion 3 and is preferably made integral therewith and not as long as the portion 3 in the axial direction of the cylinder.

Another lug 5, which may be somewhat similar to the lug I, is provided on the concave side of the portion 3 and preferably integral with the portion 3. The lug 5 is somewhat longer than the width of the strap I and it is provided with an opening 6 therethrough which is as long as the width of the strap I and is as wide as the thickness of this strap. The lower edge of the slot 6 may lie in a plane which passes through the lowermost portions of the edges of the portion 3, so that when the strap passes through the opening 6 it must be bent, and when it is held taut the stop will be securely held in position against sliding of the strap, as the bends in the strap I at the corners or edges 8 keep the strap from sliding in the opening 8 when tension is applied to the strap. When pressure is exerted on either side of the lug I in a direction somewhat parallel to the strap I, it causes the opposite corner 8 to bend the strap I more sharply, thus making it even more certain that the stop will remain in position under these circumstances.

In order to move the stop 2 on the strap I, the strap is bent where the stop is located, thus taking its upper surface out of contact with the edges 8, whereupon the strap can be pushed through the opening 6, or the lug can be moved along the bent portion of the strap while the tension on it is released.

In Fig. 3 reference character I I] indicates a tire to which an antiskid device I I, having pointed rivets I2 riveted thereto is attached. The felly I3 of the wheel and a part of one of the spokes I4 is shown with the rim I5 attached to the felly. The bent edges I6 of the arm I5 leaves grooves I'I into which the lugs 4 of the stops 2 on the straps I extend to keep the antiskid device from moving transversely around the tire. It will be understood that the ends of the straps I may be connected, as for example by means of the buckle I8, so as to keep the antiskid device II on the tire.

For example, a strap about one eighth of an inch thick and one and a quarter inches wide, made of fabric that is somewhat stiff but is flexible enough to be bent by hand, and having a stop made of iron thereon with the portion 3 about three sixteenths of an inch thick, and one and a half inches long and an inch and a quarter in arcuate width curved on a one inch radius with the lug 4 a quarter of an inch thick and the lug 5 three sixteenths of an inch thick, has been found to be sufficient to keep antiskid devices of the sort shown. in Fig. 3 from moving circumferentially on the tires when used, as shown in this Fig. 3, on heavy trucks even when they turn sharp corners.

I claim:

1. In a device of the character described, a curved imperforate plate, lugs on opposite sides of said plate, and a strap, the lug on the inner concave side of said plate intermediate its lateral edges for holding said plate in adjusted positions on one side of said strap, and a stop lug on the opposite side of said plate from said strap.

4. In a device of the character described, a metallic member having a concave side, a holding member attached to said concave side intermediate its edges, said holding member having a passageway therethrough in proximity to said concave side.
